What does skylight installation in Castle Douglas involve?
For Castle Douglas homes and buildings we offer skylight installation: survey, supply and fit — new openings, extensions and fit-only work. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Short winter days in Scotland make every square metre of overhead glass count, so rooflight sizing matters. Typical uses for skylight installation include new extensions, new openings and fit-only jobs.
Castle Douglas sits about 14 km from Kirkcudbright and 25 km from Dumfries, and we cover the whole DG7 postcode district and the roads in between.

Consents for skylight installation in Castle Douglas
Scottish householder permitted development (Class 2B, other external alterations) can cover a rooflight that projects no more than 1 metre from the roof, but the right does not apply in conservation areas. Flats and tenements are outside householder permitted development, so check with the planning authority first.
Scotland's Technical Handbook (section 6) asks for windows, doors and rooflights in an extension to average 1.4–1.6 W/m²K, with no single unit worse than 3.3 W/m²K. Replacing a rooflight, frame included, does not need a building warrant, but the work must still meet the building standards.

Common questions
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Is the survey free?
Yes, for new installations. Repair visits are charged.
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
Will I need planning permission in Castle Douglas?
In Scotland most rooflights on houses fall under Class 2B permitted development; in a conservation area, or on a listed building, consent is needed.
How do I book a survey in Castle Douglas?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
